Float charge: Maintaining 100%. There are some things that you can do with an AGM charger that you simply should never try doing with a standard battery charger. Overcharging an AGM battery can lead to reduced battery life. I.C’s control and regulate current and voltage and automatically switch from the higher fast charger voltage to the lower float voltage when batteries are very close to be fully charged. Please set your charger to the type of chemistry your battery is. The special AGM battery chargers comprise of microprocessors for collecting information from the battery to adjust the current and voltage accordingly.

Mastervolt gel (2 V, 12 V) and Mastervolt AGM (6 V, 12 V) batteries should be charged with a voltage of 14.25 V for 12 V systems and 28.5 V for 24 V systems. In this stage, the charger maintains a lower float voltage between the battery terminals. Perfect for RVs, ATVs and other seasonal vehicles. As a rule, do not equalize AGM or Gel batteries. The purpose of this stage is not to add any charge, but rather counter self-discharge and keep the battery full.. For a 12V system, they do not like 15.5 V Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery.
